Undefeated welterweight contender Kell Brook (24-0, 16 KOs) is taking aim at all of the world champions. This Saturday, Brook faces 34-year-old Polish veteran Rafal Jackiewicz (38-9-1, 19 KOs) at the Ponds Forge Arena in Sheffield. The fight is a WBA world title eliminator, but there is no indication if a bout with WBA champ Vyacheslav Senchenko can easily be made.

Brook's domestic rival Amir Khan is making a move to 147 in early 2012. Brook set a goal of winning a major world title, with the overall goal of encouraging Khan to fight him. Khan, based on his past interviews, refuses to fight Brook unless he dumps current promoter Eddie Hearn. If Brook is unable to bring Senchenko to Sheffield, he may be forced to challenge one of the other champions, like IBF titleholder Andre Berto.

“I have to win and I have to look good – I think this guy is perfect for me,” ­insisted Brook to Steve Bunce. “The world champions at my weight are making excuses or asking for too much money."
